Constraint rules prevent invalid data entry during editing. In this case, a constraint rule ensures that only valid amperage values are allowed based on the chosen wire gauge. If an invalid amperage is entered, the rule will block the edit and display an error message.

Validation rule (Option C) flags invalid data but doesn’t prevent edits from being saved.

Therefore, the correct answer is B.
